Title:
FULL-CURRENT CONTROL BATTERY MODULE AND FULL-CURRENT CONTROL BATTERY ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/179734
Kind Code:
A1
Abstract:
Disclosed in the present invention are a full-current control battery module and a full-current control battery energy storage system, belonging to the field of electrical power energy storage. The full-current control battery module comprises an energy transmission control unit, a relay energy unit and a current control unit, wherein in a charging state, the energy transmission control unit is used for controlling electrical energy, which is output by an external direct-current system, to be transmitted to the relay energy unit; the current control unit is used for performing closed-loop control on a charging current of the battery module according to average energy, which is stored in the relay energy unit, and cutting off a charging loop when the voltage of the battery module exceeds a charging cut-off voltage; and in a discharging state, the current control unit is used for performing closed-loop control on a discharging current of the battery module according to the average energy, which is stored in the relay energy unit, and cutting off a discharging loop when the voltage of the battery module is lower than a discharging cut-off voltage. In the present invention, separate current control of each battery module can be realized, and the effect of a current generated by an external direct-current system on the battery module is isolated.
